build failed for i686-pc-linux-gnulibc1 X sparclite-coff

[Joern Rennecke <amylaar at cygnus dot co dot uk>]

I tried to build a i686-pc-linux-gnulibc1 X sparclite-coff cross-compiler
toolchain from the egcs trunk sources, and it failed in objc:

I configured with --target=sparclite-coff, and then did a 'make all-gcc' .
